SPECIFICATION forming art of Letters Patent No. 540,786, dated June 11, 1895.

Application filed April 10, 1895. Serial No. 545, 50. (No model.)

To all whom it may concern.-

Be it known that we, W ILHELM F. D; GREN- INGER and FREDERICK SCHVVENKEL, citizens of the United States, residing at Bridgeport, in the county of Fairlield and State of Connecticut, have invented certain new and useful Improvements in Attaching Shades to Rollers; and we do hereby declare the following to be a full, olear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide novel means for attaching shades to rollers which shall render the use of tacks unnecessary, shall be applicable to wide or narrow shades, will hold the shade just as firmly at the center as at the ends, will be sosimple as to enable any person skilled or unskilled to attach a shade to a roller and which shall beso inexpensive as to be Within the reach of all.

With these ends in view We have devised the novel device for attaching shades to rollers of which the following descriptionin connection with the accompanying drawings is a specification, numbers being used to designate the several parts.

Figure 1 is an elevation, partly in section, illustrating the use of our novel devicein attaching a wide shade to a roller, a supplemental clamp being applied at the center of the roller; Fig. 2, an end elevation as seen from the right in Fig. 1; Fig. 3, a section on the line 00 a: in Fig. 1, looking from the right, the supplemental clamp being removed; Fig. 4, a similar view with the supplemental clamp in place the same as in Fig. 1; Fig. 5, a section on the line y y in Figs. 2 and 3, the shade being removed; Fig. 6, a corresponding view of the other end of the roller, the winding device being in section; and Fig. 7 is an end elevation corresponding with Fig. 6, the cap being removed.

1 denotes the roller and 2 the shade. The roller which may be of metal or wood is provided with a longitudinal groove 3, at one end with a winding device designated as a whole 6. The winding device and the trunnion engage suitable fixtures, not shown, upon a casing in the ordinary manner. I

B denotes the shade clamp which is made of sheet metal and is curved to correspond approximately with the curvature of the roller and is provided at one end with an eye 7 adapted to receive a rod 8 and at the other end with a socket 9 formed by curving the metal of the clamp back upon itself, said socket being adapted to receive the end of the shade.

1O denotes caps having openings 11 at the center through which the trunnion and the engaging shaft of the winding device pass and which are adapted to slide over the ends of the roller, covering plate 4 at one end and the winding device at the other end and also sliding over the ends of the shade clamp whereby the latter is locked in position upon the roller. I

In attaching a shade to the roller the end of the shade is inserted in socket 9 as clearly shown in Figs. 3 and 4. In attaching ordinary sized shades the rod 8 may or may not be used in eye 7. If used one end of said rod is inserted in groove 3 passing under the cap a, of the winding device as clearly shown in Fig. 6, the other end of the. rod being then dropped into oblique slot 6 in plate 4. The shade is then folded over the end of the metal of the clamp the bottom of the socket being downward and the shade hanging downward and the clamp is laid against the roller as in Figs. 3 and 4. The clamp is then looked securely in position by passing caps 10 over the ends of the roller and over the ends of the clamp, a fold of the shade being thus held between the clamp and the roller. The caps in practice are made to go on tight enough so that they will stay in place by friction without danger of their slipping off. It will be seen that the caps not only hold the clamp firmly in position but also prevent the rod if used from slipping outunder anycircumstances. When the rod is used one end of the clamp is attached to the roller by the engagement of the ends of the rod with cap a and oblique slot 6 in plate 4, leaving the socket end free so that the end of a shade may be inserted in the socket or removod therefrom without detaching the clamp from the roller.

In order to prevent the possibility of the clamp dropping away from the roller in case of the attachment of a heavy shade to a long roller I provide one or more supplemental clamps c which are curved to partially inclose the roller and to inclose the shade clamp, the supplemental clamps of course extending more than half way around the roller and each clamp being provided with an eye 12. When supplemental clamps are used I out openings 13 in the shade clamp removing eyes 7 entirely at the openings so that the eyes 12 of the supplemental clamps will register with the eye of the clamp on opposite sides of the socket as is clearly shown in Fig. 1 in which we have only shown one supplemental clamp, that being ordinarily quite sufficient to hold any shade on a roller, although more may be used in case of an exceptionally wide shade. The rod 8 is passed through the eye 7 and also through eye 12 as clearly shown in Fig. 1 so that the same rod will hold both the shade clamp and the supplemental clamp in place.

Having thus described our invention, we claim- 1. The combination with a shade roller having a longitudinal groove 3 and a clamp having at one end an eye adapted to lie in said groove and at the otherend a socket adapted to receive the end of a shade, of caps 10 which pass over the ends of the roller and over the ends of the clamp whereby the clamp and with it the shade are securely locked to the roller.

2. The combination with a shade roller having a longitudinal groove 3 and a clamp having at one end an eye adapted to lie in said groove and at the other end a socket adapted to receive the end of a shade, of a rod adapted to pass through the eye, means for securing the ends of the rod at the ends of the roller, and caps 10 adapted to pass over the ends of the roller and over the ends of the clamp the latter clamping a fold of the shade between itself and the roller.

3. The combination with a shade roller having a groove 3, and a clamp B having at one end an eye adapted to lie in the groove and an opening 13, and at the other end a socket adapted to receive the end of the shade, of a supplemental clamp 0 having an eye 12 adapted to lie in the opening, said clamp 0 partially inclosing the roller and inclosing clamp B, a rod adapted to pass through eyes 7 and 12, means for securing the ends of the rod at the ends of the roller and caps 10 adapted to pass over the ends of the roller and over the ends of clamp B the latter clamping a fold of the shade between itself and the roller.

In testimony whereof we affix our signatures in presence of two witnesses.
